Definitions

  • the present invention refers to a gob distributor for glassware forming machines, which effectively and efficiently regulates the different moves of the distribution chutes towards the respective glassware forming stations.
  • the gob distributor is reduced in size and is more easily built than any other known gob distributor.
  • portions of glass are obtained from a glass melting source that provides a continuous flow of glass, which is continuously cut, by means of a suitable cutting mechanism, into portions called “gobs”, which are distributed by means of a gob distributor in one or more cavities of a plurality of glassware forming stations, generally six, eight, ten or twelve, which constitute the machine, with the advantage that the distribution can be reprogrammed in the event of malfunction, maintenance of any section or by under stretching of glass.
  • the known gob distributors of the prior art usually contain one or more movable chutes, each supported with an axis shaft. These chutes are aligned in manner that they move through suitable gear-based mechanisms, these mechanisms are controlled by a moving cam that causes chutes to move together between one glassware forming station and the next, in a predetermined glass gob delivery sections of the machine.
  • This stem is supported by a control cam that, according to its profile, makes curved deflector scoops move radially between one molding station and the next, to deliver the gobs through a series of fixed channels that guide them towards the molds of each forming stations of the machine.
  • the control cam is turned at the same time by means of a crown and a screw, which is coupled to a shaft.
  • the shaft is rotated by a synchronous motor that rotates the cam at a constant speed, synchronized with operating controls, for example, a timing drum controlling several operations on each station of the forming machine.
  • the gob distributors known in the prior art already eliminate the use of a drive cam to control the movement of the mobile channels of a glass gob distributor and, instead, use electronic or stepping motors, as well as an electronic control system, as illustrated in U.S. Pat. No. 4,357,157, granted to Luis Cardenas Franco, et al, on Nov. 2, 1982, and assigned to Investigacion FIC Fideicomiso.
  • the distributor includes a pair of curved distribution scoops, arranged one behind the other, the front scoop is provided with a ring support resting on a shaft, while the rear scoop passes through said ring and resting on a second shaft, to achieve the rotation movement at predetermined angles.
  • the distribution scoop shafts pass through a common support and coupled by means of appropriate couplings to stepping motors, which run completely independently by providing motions perfectly measured by the number of steps fed to each motor.
  • stepper motors are operated by an electronic control system synchronizing the delivery movement of the scoops with respect to each section of the forming machine.
  • gob distributor of the type using programmable means is described in the U.S. Pat. No. 4,687,502 granted to Robert J. Douglas et al., and assigned to Emhart Industries.
  • This distributor includes a modification to the distribution system described in U.S. Pat. Re 28,759, assigned to such company.
  • the main features of said gob distributor include the use of a servomotor, which is a direct current reversible motor, to position a rack and control the angular movement of the curved gob delivery scoops.
  • a servo motor is controlled by a servo position control mechanism, which is also controlled by the motion profile through a computer that can be manually adjusted.
  • This gob distributor can be considered to be manufactured in two sections, a replaceable section that includes a housing with a pair of toothed sprockets respectively coupled to a pair of feed chutes. These pinions are also coupled with a rack, which makes the scoops move angularly between one position and another; and a fixed section containing a servo motor and a rotary linear motion impeller, which can be coupled to the main structure of the glassware forming machine.
  • U.S. Pat. No. 5,637,128 by Gaspar Rodriguez Wong et al refers to a gob distributor for glassware forming machines or other materials, which includes: at least one curved distribution scoop mounted on a vertical rotary axis for each gob simultaneously supplied by a distributor, each scoop has its upper end aligned at all times with each respective hole of the glass molten gob feeder and moves radially so its end matches in a predetermined order with the upper ends of the fixed channels of a forming machine which carry the gobs to the respective molds of the sections of such machine; a housing is composed of at least one gear which rotates on its axial axis, in conjunction with a central shaft coupled to the housing which are joined together with the vertical axis of each distribution scoop; a rack coupled to match the gears of each distribution scoop to move these gears with a rotational movement and thus provide a simultaneous and synchronized rotation to each scoop; and, a rotary driving member coupled to
  • the motion control of the curved scoops can be handled with great security, and the angular position programming (adjustment) can be easily controlled.
  • Another objective of the present invention is to provide a gob distributor for glassware forming machines, which accepts different motion orders for the distribution scoops without having the need to disassemble the mechanism.
  • An additional objective of the present invention is to provide a gob distributor for glassware forming machines which, since it is built in a more compact form (reducing its length and size to almost half of the known distributors), reduces the problem of wear mechanisms, thus avoiding problems of sudden motions during the distribution of the gobs to the different sections of the glassware forming machine.
  • An additional objective of the present invention is to provide a gob distributor for glassware forming machines, which can be easily modified to convert it for use in double, triple or quadruple cavity.
  • An additional objective of the present invention is to provide a gob distributor for glassware forming machines that, since each shaft and their respective motor are independent allowing to perfectly align each scoop from double cavity with each parison mold, maintaining a perfect alignment for a perfectly centered load.
  • Another objective of the present invention is to provide a gob distributor for glassware forming machines where the scoop holders or arms of each scoop move completely independently, each scoop holder being inserted in the opposite direction to the other at 180° and in a relation one to the other, allowing a greater fan angle equal to or greater than 140°, which is superior to those made by the distributors of the previous art.
  • Yet another objective of the present invention is to provide a gob distributor for glassware forming machines, which provides a motion of the distribution scoops with no sudden changes of acceleration.
